I know ACI 318 has guidelines on stud rails for flat slabs for shear reinforcement (at columns).
We often work with one way joist slabs. Joists are 2ft o/c, 4.5" wide and 10" deep. These joists often need shear reinforcement (1st and last third of the 25ft span - roughly speaking).
#3 Stirrups...
I have been using Enercalc T-beam to design these and it works OK. A bit sluggish and shear is not what it should be for one-way joist slabs.
Is there a better software the can do these? Curious what others are using - apart from manual work.
Trying to find moment of inertia in^4) for a steel beam that looks like the attached (22 gauge steel).
Finding MOI for any beam is easy if it has no side holes.
Not sure if it helps, but I can actually have SolidoWorks FEA analysis done to get the total deflection.
I need to find the MOI...
Hi,
For some reason i have always been under the impression that you simply cannot weld nelson studs to top of a steel stud wall? I have a section of building where the interior bearing wall is done with light gauge 2x4 steel studs and will carry the weight of a concrete floor from above. All...
Need some 'simple/basic' help here...
An engineer in Greece wants to introduce load-bearing beams (14"Wx24"D) on a small 28'x50' residential 2 story project.
Saying that the 1-way ribbed concrete floor cannot handle the seismic zone III (max. horizontal acceleration A max = 0.25g)
However...
Hello,
I am not with Helix; just wanted to make sure no one was looking at plastic fibers.
There are a few studies out there but I am not sure if this is the way to go? Can anyone give me their opinion on this please?
Thanks!
Hello,
I could swear I saw a reference in ACI-318 about shear stirrups allowed to project into the minimum required reinforcement cover. In other words the 3/4" cover would be only applicable to primary bars exempting #3 bars which would have less than 3/4"...
Can anyone help... I have spent...
